CY62158H is a high-performance CMOS low-power (MoBL) SRAM device with embedded ECC. Device is accessed by asserting both chip enable inputs – CE1 as LOW and CE2 as HIGH. Write to the device is performed by taking Chip Enable 1 (CE1) LOW and Chip Enable 2 (CE2) HIGH and the Write Enable (WE) input LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A19).
